Ans: Imagine you are standing in an ancient Indian classroom thousands of years ago.
The teacher, with a sandboard in front of him, is explaining numbers using tiny stones.
He picks up a few and arranges them carefully — one, ten, hundred, thousand — and
with each arrangement, he creates a whole new world of calculation. This was not just
mathematics; it was the birth of a unique notation system — the Indian Number
System, a treasure India gifted to the entire world.
Today, whether we use computers, mobile phones, or calculate budgets, every digit
traces its roots back to this system. But like every invention, it comes with its own
advantages (merits) and disadvantages (demerits). Before diving into them, let’s
understand what the Indian Notation System really is.
Understanding the Indian Notation System
The Indian Notation System is a method of representing numbers that divides them into
groups based on the Indian way of counting. It uses place values like ones, tens,
hundreds, thousands, lakhs, and crores.
It is commonly used in India, Bangladesh, Nepal, Pakistan, and Sri Lanka.
For example:
• 1,000 → One thousand
• 10,000 → Ten thousand
• 1,00,000 → One lakh
• 10,00,000 → Ten lakh
• 1,00,00,000 → One crore
The commas are placed after every two digits starting from the right, except the first
group which contains three digits.
This pattern continues as the numbers grow.
